cleanup(netx): stop using most netxlite resolver internals (#797) 
This diff modifies netx to stop using most netxlite resolver internals
but the internal function that creates a new, unwrapped system resolver,
which will be dealt with in a subsequent pull request.

Package github.com/ooni/probe-engine/netx

OONI extensions to the net and net/http packages. This code is used by ooni/probe-engine as a low level library to collect network, DNS, and HTTP events occurring during OONI measurements.

This library contains replacements for commonly used standard library interfaces that facilitate seamless network measurements. By using such replacements, as opposed to standard library interfaces, we can:

  • save the timing of HTTP events (e.g. received response headers)
  • save the timing and result of every Connect, Read, Write, Close operation
  • save the timing and result of the TLS handshake (including certificates)

By default, this library uses the system resolver. In addition, it is possible to configure alternative DNS transports and remote servers. We support DNS over UDP, DNS over TCP, DNS over TLS (DoT), and DNS over HTTPS (DoH). When using an alternative transport, we are also able to intercept and save DNS messages, as well as any other interaction with the remote server (e.g., the result of the TLS handshake for DoT and DoH).

This package is a fork of github.com/ooni/netx.
